When we are repairing our patient hard drives and recovering the data, it’s a must we have a correct analysis process and have one accurate conclusion on what’s wrong with the hard drives. Never do as you wonder when you are not sure of this one. Recently we have some clients who have shared with us some of their embarrassing experience before having our hdd repair tools and we are here sharing with all users so that you may avoid the same mistakes and destroy your data.

Let’s check the following failures and symptoms:

* The patient hard drives click each 3-4 seconds; * The hard drives keeps busy and not ready; * A drive produces knocking sounds at the start and keep clicking all the time; * A drive after power-on knocks for a long while and then reaches readiness having stopped the spindle motor; * A drive produces clicking three times and then spin down; * A drive that is not responding at all.

After you read above symptoms, are you able to tell what are the real causes? Clicking must be caused by head damage or by firmware corruption? What did you usually do to fix above failures and symptoms? Are you able to fix them at a high success rate?

For experienced users,they can judge some symptoms easily by listening to the hdd clicking. For example, the platter is even scratched with noises, the hard drives keep clicking all the time, sometimes, the drive is not responding at all can be platter scrtaches too.

Usually if the drives knocks and become ready and spin down can be caused by single head damage and users can disable the head one by one to find out the damaged head and then image from good heads. If the disks click each 3-4 seconds or if it produces three clicks and then spin down, usually it’s caused by firmware failure.

But what we want to say is that to find out the real reason, the best is to use a professional hdd repair tool,not only by experience. Some hard drives have combined failures and that’s not easy to fix by experience alone. For example, users can simply use DFL-WDII hdd repair tool to judge professionally and accurately whether it’s firmware or head damaged caused clicking nosies.

It’s very risky to handle on such clicking or singing hard drives if you didn’t use a correct way and method. If you treat one head damaged clicking hard drives as one firmware damaged clicking hard drive, you will destroy the hard drives. When you fail to fix one suspected firmware damaged hard drive for one or at most two times, you should open it in a clean room environment to see if there’s head damage or platter scratches. never repeatedly work on it and try your ways to fix it in a firmware restoration way.

The following are two pictures from one client who treated the hdd failure as firmware or rom failure while it’s actually head damage and finally the data is gone forever:
